Product details
Overview
MXDA3KP36AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 36 V standoff voltage (VWM), 40.0–44.2 V breakdown range (V(BR)), and 58.1 V maximum clamping voltage (VC) at 51.6 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in industrial power interfaces.
For engineers reviewing the MXDA3KP36AE3 datasheet, MXDA3KP36AE3 pinout, MXDA3KP36AE3 application, or MXDA3KP36AE3 equivalent, key selection criteria include its 36 V working voltage, 58.1 V clamping performance at 51.6 A, RoHS-compliant e3 marking, -55 °C to +150 °C operating junction temperature, and unidirectional polarity confirmed by part nomenclature and polarity note on page 2.
Technical Context
This TVS array uses silicon avalanche diode technology optimized for fast response (<100 ps rise time) and high-energy surge handling under 10/1000 µs waveform conditions. Its unidirectional construction enables DC-biased line protection without reverse conduction during normal operation.
Designed for surface-mount vertical mounting, it delivers 3000 W peak pulse power with full surge testing per production lot and traceable wafer/assembly lot control. The device meets MIL-PRF-19500 screening options and exhibits Level 1 moisture sensitivity (IPC/JEDEC J-STD-020B) with no dry pack required.

Applications
| Industrial Power Input Protection | Automotive ECUs |
|---|---|
Use Scenario: 24 V DC power input stage in programmable logic controllers exposed to load dump and inductive kickback. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between input rail and ground to shunt surge energy before reaching DC-DC converters. Use Value: Withstands 3000 W surges while clamping to 58.1 V, protecting downstream regulators rated for ≤60 V absolute maximum. | Use Scenario: CAN bus power line protection in engine control units subjected to ISO 7637-2 Pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed on VCC line to suppress negative-going spikes without interfering with CAN signal integrity. Use Value: 2 µA standby leakage avoids battery drain; 40–44.2 V breakdown ensures reliable triggering above nominal 24 V rail. |
| Telecom Line Interface | Renewable Energy Inverters |
Use Scenario: Secondary-side 48 V DC distribution in remote radio units where induced RF and lightning-induced surges occur. IC Role / Device Role / Timing Role: Standoff-rated TVS on power feed line to absorb coupled transients from nearby antenna coupling or grounding differences. Use Value: 36 V VWM matches telecom nominal voltage; 58.1 V VC prevents latch-up in PMICs and FET drivers downstream. | Use Scenario: DC link protection in solar string inverters experiencing rapid voltage transients during grid fault clearing. IC Role / Device Role / Timing Role: High-power TVS mounted directly across DC bus capacitors to clamp voltage overshoot during IGBT switching events. Use Value: 3000 W rating handles repetitive 10/1000 µs surges common in grid-tied systems; -55 °C to +150 °C range supports outdoor enclosure operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | 600 W PPP rating, SMA package, 58.1 V VC @ 10.3 A - lower surge capacity and smaller thermal mass | Best suited for low-energy board-level ESD protection, not secondary lightning or high-current inductive switching | Select SMAJ36A only when space constraints prohibit TO-277A footprint and surge demands are ≤600 W |
| SMCJ36A | 1500 W PPP rating, SMC package, 58.1 V VC @ 25.8 A - mid-tier energy handling, same clamping but half the peak current capability | Appropriate for Class 2–3 IEC61000-4-5 protection where 3000 W is not mandated | Choose SMCJ36A when cost and thermal budget are tighter, and full 3000 W immunity is not required |
Compared with SMAJ36A and SMCJ36A, MXDA3KP36AE3 delivers double the surge energy capacity of SMCJ36A and five times that of SMAJ36A-enabling single-device compliance with IEC61000-4-5 Class 4 (42 Ω) without parallel staging or derating.

FAQ
What is the clamping voltage of MXDA3KP36AE3 and under what test condition is it specified?
The MXDA3KP36AE3 has a maximum clamping voltage (VC) of 58.1 V, measured at 51.6 A peak pulse current (IPP) under the standard 10/1000 µs double-exponential surge waveform. This value is guaranteed across the operating temperature range and reflects worst-case device behavior during high-energy transients.
Is MXDA3KP36AE3 unidirectional or bidirectional, and how is polarity indicated?
MXDA3KP36AE3 is unidirectional, as confirmed by the absence of "C" in its part number and the polarity note on page 2 stating "Odd number pins are cathodes." Pin 1 is the cathode, and Pin 2 is the anode-enabling DC-biased protection where reverse conduction must be avoided.
Does MXDA3KP36AE3 meet RoHS requirements, and what does the "e3" suffix signify?
Yes, MXDA3KP36AE3 is RoHS-compliant. The "e3" suffix explicitly denotes matte-tin plating per JEDEC standards, confirming lead-free terminations and compliance with Directive 2011/65/EU. This is documented in the nomenclature section on page 2 of RF01243 Rev B.
What is the maximum standoff voltage (VWM) and why is it critical for MXDA3KP36AE3 selection?
The maximum standoff voltage (VWM) of MXDA3KP36AE3 is 36 V. This parameter defines the highest continuous operating voltage the device blocks without clamping-so it must be ≥ the peak operating voltage of the protected line. Selecting a VWM too close to or below the nominal rail risks premature conduction and power loss.
Can MXDA3KP36AE3 be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXDA3KP36AE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with a 42 Ω source impedance, as stated in the Applications/Benefits section on page 1. Its 3000 W peak pulse power and 51.6 A IPP capability meet the 4 kV/2 Ω, 2 kV/12 Ω, and 1 kV/42 Ω test levels defined for Class 4.
